ABSTRACT

The invention relates to a sheet metal profile ( 9   a,b,    19   a,b,    22   a,b,    23   a,b,    24   a,b,    25 ) primarily intended for installation against parts of a building, for example for the protection of bargeboards ( 2 ) or other wooden component parts of the building, comprising a bent metal sheet having a central section and at least one lateral part ( 3   a,b ) with inward-folded edge sections ( 15   a,b ) at the bottom. The invention is achieved by the sheet metal profile ( 9   a,b,    19   a,b,    22   a,b,    23   a,b,    24   a,b,    25 ) being of mirror symmetrical configuration at both end sections ( 11   a,b,    17, 21   a,b ), and by the end sections ( 11   a,b,    17, 22   a,b ) being provided with an inward-facing edge ( 13   a,b,    21   a,b ) cut at an angle, that is to say one or both lateral parts ( 10   a,b,    20   a,b ) of the sheet metal profile ( 9   a,b,    19   a,b,    22   a,b,    23   a,b,    24   a,b,    25 ) are executed with angled end edges ( 13   a,b,    21   a,b ), where the angle (v) between the upper plane surface ( 12 ) of the sheet metal profile ( 9 ) and the end edges ( 13   a,b,    21   a,b ) of the lateral parts form an acute angle (v).

TECHNICAL FIELD

The present invention relates generally to sheet metal elements or sheetmetal profiles for use in covering parts of buildings. The inventionrelates in particular to sheet metal profiles that are intended to bejoined in the longitudinal direction and are accordingly configured attheir end areas so that a waterproof, durable, functional and neatlyexecuted joint is obtained when a plurality of sheet metal profiles areinstalled next to or after one another.

BACKGROUND ART

When covering a roof, for example, it is customary to install transverseplanks of wood at the gable ends of the roof and for these to constitutethe bargeboards of the roof. The gap or opening that occurs between theroof covering material and the bargeboards is often covered/bridged withthe help of profiled sheet metal covers or so-called bargeboard covers,which are bent down on both sides about a raised central section, whichcentral section is positioned above the upper side edge of thebargeboard; see FIG. 1. This downward bending is provided to guide therunoff from the cover and to protect the bargeboard from moisture.Because the bargeboard covers are supplied in standard lengths, usuallyin two-metre lengths, they must be joined together in conjunction withtheir installation on buildings whose bargeboards exceed this length,which is usually the case. Because the bargeboard covers exhibitdifferent bending on the inside and the outside, with different angles,and because they must be overlapped in conjunction with joining in orderto be waterproof, so that water does not run in underneath the coverinstalled in the lowest position, the bargeboard covers must bemanufactured in two configurations, one for right-hand and one forleft-hand installation. This requires both forms to be manufactured andkept in stock by the manufacturer, the supplier and in the shop. Thistakes up a certain amount of storage space with associated storagecosts. It is also necessary at the time of delivery to keep a closecheck on the number of right-hand and left-hand profiles to be deliveredand installed. Unfortunately, incorrect deliveries often occur inpractice, or the orderer may be mistaken in the number of covers of thedifferent configurations to be used in the installation. This involvesreturns and increased handling costs and delays the installation.

One way of avoiding this problem is not to make the cut-outs in thecover that are normally required in order to achieve good contactbetween two covers that are to be joined together, so that waterproofjoints can be achieved, yet still allowing the covers to overlap oneanother regardless of whether the installation is right-handed orleft-handed. This results in a poor fit between the component parts andthe possibility of a leaking joint occurring. In addition, such a jointis visually conspicuous and untidy.

DISCLOSURE OF INVENTION

One object of the invention is to solve the problems outlined above andto propose a sheet metal profile which, when installed and joined toother sheet metal profiles, gives a waterproof, durable and visuallyneat joint that is fit for purpose, regardless of whether they areinstalled as a right-hand or a left-hand profile on part of a building.

A further object of the invention is to simplify the manufacture andthus to reduce the production costs by reducing the number of differentsheet metal profiles, as well as the volume of sheet metal profiles,that require to be manufactured and kept in stock, which also reducesthe cost of storage and the storage area required by manufacturers,distributors, shops and tradesmen.

A further object of the invention is to propose a sheet metal profilewhich reduces the risk of ingress of water and corrosion.

A further object of the invention is to eliminate or to reduce the riskof incorrect deliveries or incorrect manufacture of the number of sheetmetal profiles required for right-hand and left-hand installation andthereby to reduce the need for transport of these components, which alsohas a positive effect on the environment.

A further object of the invention is also to enable a person who is notskilled in the art to install sheet metal profiles without specialistknowledge and without professional tools and still to achieve awaterproof and visually neat joint that is fit for purpose.

The above-mentioned and additional objects and advantages are achievedaccording to the invention with the help of a sheet metal profileconfigured in accordance with the distinctive features indicated in thecharacterizing part of Patent Claim 1.

The invention thus relates to sheet metal profiles that are configuredwith angled or notched end walls so that they can overlap othercorresponding sheet metal profiles without requiring to be pushed intospecial tracks therein and without the need for specially configuredrecesses or cut-outs which make manufacture and installation difficultand mean that installation takes a longer time because the profiles canbecome tightly wedged in one another in conjunction with joining, amongother things due to friction and/or the stick slip effect. One sheetmetal profile according to the invention is provided withdownward-folded lateral parts, of which the end walls are cut at anacute angle in relation to the upper plane surface of the sheet metalprofiles. The angle between the upper surface and the end edge of thelateral parts is preferably approximately 45 degrees, although it can,of course, be larger or smaller. A small part, preferably approximately1 cm, of the lowest edge of the lateral parts is folded up towards theinside of the sheet metal profile in order to reinforce the bottom edge.This permits good contact between joined profiles, and if, for example,an angle of 45 degrees is used for the oblique cut, the upward-foldededges form a stop for two sheet metal profiles when they are joinedtogether. If the end walls of the sheet metal profiles are punched, itis also easy to form a tongue on each upward-folded edge, which is ableto some extent to overlap/cover a part of neighbouring sheet metalprofiles and, by so doing, to lock the profiles to one another.

Further distinctive features and advantages of the invention can beappreciated from the following, more detailed description of theinvention and from the accompanying drawings and the other patentclaims.

MODE(S) FOR CARRYING OUT THE INVENTION

The invention relates to a sheet metal element or a sheet metal profileintended for installation against parts of a building and relates to,among other things, sheet metal profiles intended for covering, forexample, bargeboards on roofs. The invention relates in particular tothe configuration of the end areas of the sheet metal profiles, so thatonly one variant of a sheet metal profile is required, regardless ofwhether they are intended for left-hand or right-hand installation. Thesheet metal profiles must also be capable of being joined to one anotherin such a way that a durable, waterproof, functional and visually neatjoint is produced between the sheet metal profiles.

FIG. 1 depicts, in accordance with the prior art, a bargeboard cover 1,viewed from one of its end walls. The sheet metal profile 1 is intendedfor installation over a bargeboard 2, for example made of wood, byscrewing or nailing into the upper plane horizontal surface of thebargeboard 2 or into the lateral parts of the bargeboard 2. The sheetmetal profile 1 is provided with downward-bent lateral parts 3 a,b, ofwhich one lateral part 3 a is intended to be installed on the outer sideof the bargeboard 2, that is to say the side which faces away from thecovering of the roof, and of which the other lateral part 3 b isintended to be connected to the covering of the roof, for example toroofing tiles, roofing sheets or similar (not illustrated). Theouter/lower edges 4 a,b of the lateral parts 3 a,b are provided withupward-folded reinforcing edges or sections 5 a,b.

FIG. 2 depicts, in accordance with the prior art, two sheet metalprofiles 1 a,b prior to joining viewed obliquely from the side. Thesheet metal profiles 1 a,b are of different configuration at their endwalls 6 a,b. Both end walls 6 a,b are cut straight across at an angle of90 degrees in relation to the envisaged longitudinal axes of theprofiles 1 a,b. Arranged on one end wall 6 b, however, are cut-outs 7,one on each edge. These cut-outs 7 allow this profile 1 a to be pushedinto a second, corresponding sheet metal profile 1 b, and more preciselyinto the tracks that are formed by the upward-folded reinforcing edgesor the parts 5 a,b. The cut-outs 7 are usually located at a distance ofapproximately 10 cm from the end wall of the sheet metal profile andpermit the sheet metal profiles 1 a,b to overlap one another byapproximately 10 cm. The fact that the sheet metal profiles are cutstraight across and have straight end walls permits water to enterbetween the sheet metal profiles 1 a,b, among other things throughcapillary force, which can give rise to corrosion in the longer term,especially if the sheet metal profiles 1 a,b have been scratched ordamaged in some other way during transport or during installation, whichis a relatively common occurrence.

FIG. 3 depicts, also in accordance with the prior art, the two sheetmetal profiles 1 a,b in the joined position, viewed obliquely from theside. The joint 8 is straight and perpendicular, at 90 degrees, inrelation to the envisaged longitudinal axis of the sheet metal profile,and the sheet metal profiles 1 a,b are a good fit with one anotherthanks to the cut-outs 7 at the end wall of one of the sheet metalprofiles 1 a. However, the presence of these cut-outs 7 and the factthat the lateral parts 3 a,b of the sheet metal profiles 1 a,b are ofdifferent configuration on the inside and the outside respectively ofthe sheet metal profiles means that sheet metal profiles 1 a,b forright-hand and left-hand installation must be manufactured, kept instock and handled.

FIG. 4 depicts a side view of a sheet metal profile 9 according to theinvention, in this case a bargeboard cover. It can be appreciated fromthe figure that the lateral parts 10 a,b of the sheet metal profile 9,of which only the lateral part 10 b is visible in this figure, areprovided at both of their end sections 11 a,b with an end edge 13 a,bcut at an angle, which is cut inwards, that is to say so that the upperplane surface 12 of the sheet metal profile 9 forms a projecting part inboth directions and one or both lateral parts 10 a,b of the sheet metalprofile 9 are configured with an angled end edge 13 a,b, where the anglev between the upper plane surface 12 of the sheet metal profile 9 andthe end edge 13 a,b of the lateral parts forms an acute angle v. Thesheet metal profile 9 is also of mirror symmetrical configuration atboth end sections 11 a,b, and the angle v of the end edge 13 a,b inrelation to the upper plane surface 12 of the sheet metal profile 9 isapproximately 45 degrees at this point. This angle v can be eitherlarger or smaller than 45 degrees, although it should preferably liewithin the interval of 30-60 degrees.

FIG. 5 depicts in a side view, viewed obliquely from above, two sheetmetal profiles 9 a,b according to the invention, in this case bargeboardcovers, which are in the process of being joined together. Any sheetmetal profile 9 a,b at all can overlap the other sheet metal profile 9a,b thanks to the configuration of the end section 11 a,b. One and thesame sheet metal profile 9 a,b can thus be utilized both forright-handed and for left-handed installation, and only a single variantof the sheet metal profile 9 a,b is necessary. This reduces theproduction cost and the cost of storage, transport and handling.

FIG. 6 depicts a side view, viewed obliquely from above, of the twobargeboard covers 9 a,b according to the invention in the joinedposition according to FIG. 5. In this case, the right-hand sheet metalprofile 9 b overlaps the left-hand sheet metal profile 9 a. Thanks tothe lateral parts 10 a,b that are cut at an angle, a joint with a goodfit and contact between the sheet metal profiles 9 a,b is achieved,which provides a waterproof and visually neat joint.

FIG. 7 depicts the two bargeboard covers 9 a,b according to theinvention joined together according to FIG. 6, but viewed from below inthis case. It is evident from this how the inward-folded edges 15 a,b onthe right-hand sheet metal profile 9 b constitute an exact space toaccommodate the left-hand sheet metal profile 9 a, so that the profilematerial in the sheet metal profiles 9 a,b can lie fully against oneanother after installation and do not form a gap or a space between theprofile surfaces.

FIG. 8 depicts an alternative variant of a sheet metal profile 16according to the invention. In this case, the end walls 17 of the sheetmetal profile have been punched out and configured with tongues 18 a,bor locking plates which permit one of the sheet metal profiles 9 a to bepushed in to some extent into the second sheet metal profile 9 b,thereby achieving a guiding and retaining effect. This facilitatesinstallation and keeps the sheet metal profiles 9 a,b next to oneanother when they are screwed or nailed in place, for example to abargeboard (not illustrated here).

FIG. 9 depicts another embodiment of sheet metal profiles 19 a,b, viewedobliquely from the side, being in this case so-called roof end plates,with the end edges 21 a,b of the lateral profiles 20 a,b cut at anangle. The figure depicts two sheet metal profiles 19 a,b which are inthe process of being assembled together.

FIG. 10 depicts the roof end plates 19 a,b according to FIG. 9, butviewed from below in this case.

FIG. 11 depicts a further embodiment of sheet metal profiles 22 a,b, inthis case two upper tinplates prior to joining, viewed from below.

FIG. 12 depicts a further embodiment of sheet metal profiles 23 a,b, inthis case two stand-up sheets prior to joining, viewed from below.

FIG. 13 depicts a further embodiment of sheet metal profiles 24 a,b, inthis case two ridge caps prior to joining, viewed from below.

FIG. 14, finally, depicts yet a further embodiment of a sheet metalprofile 25, in this case a window ledge, viewed from below.
